I would like to thank
Cyowari for this
map, which help me a lot in the location of tribes and cities. This map also got a lot of influence from Alternate History Hub
video on the subject (there are like 3 of them but I link the first one)
Rome was once a promising city, having expanded through parts of Italy, everything seems to be going fine for them, up until in the year 390 BC, when several Gallic tribes attacked the city, and sack the entire city, where they decided that in fear of possible retribution, to destroy the entire city, burning it to the ground with only a few surviving. Those few fled down south to found the city of Rume. Rume lasted for a few more decades as a small city-state, up until their conquest by the Etruscans. Down south, Carthage, once a small Phonecian colony in North Africa, has grown over the centuries to become the superpower of the Mediterranean Sea, having land in Iberia, Southern Italy, North Africa, and as far east as the Ionian Islands. Having created a trade empire, they grew rich trading with several tribes up north as they began to evolve into cities and eventually petty kingdoms. The Carthaginians would soon look towards the east to Egypt and the Greek states, in hopes of expanding their trade and influence there. The Greek states with the decline of the Macedonian Empire would continue to fight against each other, eventually uniting under 3 states, Athens, Sparta, Crete and Ambracia. Macedonia would see itself under decline but by 815 the kingdom continues on despite its noticeable state. Up north, the Illyrians and Dacians who were once squabbling tribes have united into hereditary kingdoms as well as taken over several Greek colonies. The Gauls after the destruction of Rome would continue to see themselves squabble with other tribes, who eventually evolve into petty kingdoms. Soon they would unite with Senones (having created a city) being their new capital. The Germanic tribes would see themselves expanding south into the Alps, assimilating several Celtic tribes there. Eventually, they too united under a monarch, and regularly go to war with their rivals, the Gauls. The Pannonians having been split from the rest of the Celts by the Germanics would become a hyper militarized state with fears of being invaded by the Germanics or the Dacians. The Huns like in our timeline continue to expand into Eastern Europe and the Caucasus, and although they continue on, have seen a decline in power and have lost several territories to other kingdoms. The Persians under the Sasanians would expand into Anatolia but end their expansion there knowing the Greeks as well as the Carthage, a major rival to them. The Armenians and Colchis remain neutral to the Persians but don't like the Huns who have attempted to invade them. Egypt is still a powerful kingdom in North Africa, although their relations with Carthage remain mixed between allies at one point and enemies at other. Judea still remains with the Egyptians and Arabs not really caring about them to do anything. The Ummayad Caliphate is still around but with a stronger Persia, they have less of an interest to expand up north into the Levant. Religion wise Christianity and Islam still exist, however they are much smaller. With Christianity being in Armenia, the Greek States, several parts of the Levant, Judea and Egypt. Meanwhile, Islam is mostly in the Ummayad Caliphate, parts of the Levant, parts of Persia, and parts of Egypt and a small minority in Carthage. The rest of Europe and North Africa remain pagan with the older Celtic, German and other religions remaining alive and well. Carthage while the power of Europe may see itself fracture as all empires do, and remain to be seen yet.
